Application filed November 28, 1921. Seria1 No. 518,355.

To all whom it may concern:

Be it known that I, OSCAR CONRAD BALD- WIN, a citizen of the United States, and a resident of Winfield, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Lubricating Systems, of which the following is a specification.

My invention is an improvement in lubricating systems of the t pe more particularly adapted for use on ord automobiles.

An important object of my invention is to provide a device of the above named character which is constructed to be placed over the ordinary opening in the transmission case so that the original construction of the case and cover is not altered.

A further object is to provide a device of such' a character which can easily be attached to the transmission casing, andwhich when in position will collect theoil from the'fly wheel within the casing whereby the oil will pass through a strainer and thence into the crank case.

Another object is to provide a device of the above named character which is simple of construction and easy to manufacture.

Other objects and advantages of my invention reside in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed, reference being had to the accompanying drawings, in which,

Figure 1 is a perspective view of a transmission casing showing the device applied and the cover o fi',

Figure 2' is a; top plan view of the same with part of the casin broken away showing the inlet pipe in c ose proximity to the fly wheel.

Figure 3 is a side elevation showing the pipe running from the transmission casing and communicating with the crank case,

' and Figure 4 is an enlarged sectional view of .the device showing the same applied above the opening in the transmission cover.

In the drawings, .1 represents a transmission casing which carries lubricating oil 2 to the level shown when the engine is running under normal conditions. A fly wheel 3 revolves in the oil and as-it moves upward carries a small quantity of the oil with it.

The cover plate a is removed from the casing for the purpose of attaching the lubricating device. o

The lubricating device comprises a body or receptacle 5 of thesame length and width as the cover plate. This receptacle is interposed between the cover plate and the transmlssion casing. Bolt holes 6 are provided in the receptacle so that they coincide with the bolt holes in the casing. -Thus when the cover plate is placed over the oil receptacle all the corresponding holes coincide, and the cover plate and receptacle may be securely held in place by the bolts 7. The bolts 7 will be of greater length than the bolts originally used in holding the cover plate to the casing. The receptacle is provided with the usual opening 0 for the admission of new oil.

The receptacle 5 is provided with anin let pipe 8 having its mouth 9 in close proximity to the outer circumference of the fly wheel and approximately parallel to the length of the pipe. This inlet pipe conveys the oil collected from the fly wheel to a chamber 10 which is elon ated above the inlet pipe as shown at 11. his elongatedportion is provided to accommodate an excess of oil.

which might be forced into the receptacle when the engine is running at high speed for a considerable length of time. -When the oil reachesthe main chamber 10 it passes by gravity through a screen or strainer 12 which is placed before the outlet 13 in the wall of the receptacle. For convenience the outlet is preferably arranged near the lower corner of the receptacle as shown and is adapted to receive an outlet or conveyor pipe 1.4 which conveys the strained oil to a lower level in'the crank case as shown at 15.

It will be noted from the foregoing that the device described is purely an attachment and does not alter the original construction of the transmission case. Although the device as herein shown is preferably adapted v for use on Ford automobilesit is not restricted to such automobiles.

In use, when the fly wheel rotates in the oil, small uantities of the oil will adhere to the fly w eel and will be carried upwardly a short distance. As the speed of the fly 10s wheel increases the oil will be carried higher until it tends to liberate itself from the fly wheel by the momentum of the latter. This chamber 10.

will occur near the mouth of the inlet pipe 8 and the oil will have a tendency to enter the mouth where it will beconveyed to the The oil will flow down the inlet ipe, which is arranged to slope'downward y from the. month, by gravity and partly by its own momentum. When the oil passes through the strainer 12 and into the pipe 14:, it is in a much cleaner condition when 1t enters the crank case.

It will benoted that when the oil enters the mouth of the inlet pipe 8 it is conveyed by gravity to the crank case.

Although I have herein shown and described only one form of device embodying my invention, it is to be understood that various changes and modifications may be made herein 'without departing from the spirit of the invention or the spirit and scope of the appended claims.

What I claim is: 1. -A transmission casing adapted to carry emes a lubricating oil at a convenient level, a fly wheel rotatable therein, and a cover for the casing comprising an inclined receptacle having-a main and auxiliary compartment, the auxiliar compartment being inclined longitudinall y above an inlet pipe, an inlet conveyor pipe arranged below the auxiliary receptacle, said inlet having a mouth arranged in close proximity to the outer circumference of the fly wheel and adapted to collect such oil as may be brought up and lubricated by the movement of the fly wheel, an outlet for the main receptacle, a screen arranged before the outlet and a cover plate for" the receptacle.

2. A device of the character described comprising a main receptacle, an auxiliary receptacle formed as an extension to said main receptacle, an inlet pipe arranged below the auxiliary receptacle and opening into it and an outlet for the main receptacle.

OSCAR CONRAD BALDIVIN.
